NCT01608763

Brief Summary

The major objective of this project is to conduct a randomized controlled trial comparing the impact of the normative feedback and other personalized feedback components of the Check Your Drinking (CYD) Internet-based intervention in the general population. Eligible problem drinking participants will be randomly assigned to one of four conditions in a 2 by 2 design - to receive just the normative feedback component of the CYD intervention, just the other personalized feedback information, to a no intervention control condition, or to receive the full CYD intervention. The no intervention control condition will not be sent any intervention materials but will instead be sent a list of the different components of the CYD feedback and will be asked to think about how useful they would find each of them. All participants will be followed-up at 3 months.

Study Arms (4)

Full personalized feedback

EXPERIMENTAL

Participant provided with the full CYD personalized feedback summary.

Behavioral: Check Your Drinking (CYD) personalized feedback intervention

Only normative feedback

EXPERIMENTAL

Participant provided with just the normative feedback component of the CYD personalized feedback summary.

Behavioral: Check Your Drinking (CYD) personalized feedback intervention

Just other personalized feedback

EXPERIMENTAL

Participant provided with all the other personalized feedback components of the CYD intervention (i.e., no normative feedback).

Behavioral: Check Your Drinking (CYD) personalized feedback intervention

No intervention control

NO INTERVENTION

Participant provided with a list describing the components of the CYD intervention but not provided any personalized feedback.

Interventions

The CYD provides problem drinkers with a personalized summary of their drinking that compares his or her drinking with that of the general population. The CYD also provides an assessment of the severity of the person's drinking problem.
